Abstract

A barbed barrier in the form of a mesh 10. The mesh has a number of barbs attached, for example, at intersections of the mesh. The mesh is easily deployable and can be used in many environments to hinder unauthorised entry to, or exit from, a prohibited area. It may be used as fencing, to cover a wall, or laid on the ground, in which case it may be dispensed from a roll on the back of a vehicle. <IMAGE>

Description

BARBED BARRIERS This invention relates to barbed barriers.

For many years barbed wire has been used to prevent animals and people from leaving or- entering restricted areas. For example, the military use coiled barbed wire to secure military establishments or hinder access to other areas. The barbed wire coil is difficult both to deploy and to remove from the required location. The coil is generally provided in a relatively compressed form and has to be stretched out when deployed. In addition if the coil of barbed wire is to be relocated, it is quite a difficult task to re-compress the coil and transport it to the new location.

When either barbed wire or barbed wire coils are used, fence posts or- the like are often required either to support or locate the barbed wire in the appropriate place. This can be inconvenient and can increase the cost of using this type of security barrier. In addition the fence post can be climbed and used to cross the barrier.

According to the present invention there is provided a mesh having one or more barbs attached thereto.

The advantages of such a barrier is that it can be used without fence posts or the like. In addition the barrier is relatively easv to deploy and to remove from its location.

reference will now be made by way of example to tulle accompanying dl-awillgs in which: Figure 1 is a diagram of a barbed mesh according to one embodiment of the pr-esent: invention; Figure 2 is a side view of the Figure 1 mesh; Figures 3 to 6 are diagrams illustrating various uses of the Figure 1 mesh; Figure 7 is a side view of a possible storage and dispensing system for the mesh.

Figure 8 is a rear view of the Figure 7 dispensing system.

Referring to Figures 1 and 2, a barbed mesh is shown generally at 10. The mesh comprises a plurality of wires 12 which cross a plurality ol wires 1S at ioints 16. At the joints are one or more spikes or barbs 18 which extend away from the mesh to one 5 side of the mesh, or alternaíively to both sides of the mesh. Where more than one spike is provided at a joint, they may be splayed.

Each spike may be formed by taking a length of wire with sharp ends and winding its centre position around the mesh ioint, so that the sharp ends project from the mesh, or in other ways, such as welding.

The mesh may be of, for example, galvanised steel or of any other appropriate material. Also, the mesh may be formed from expanded plastics material, with metal spikes attached thereto.

The physical dimensions of the mesh, the distances between joints and the number of spikes may all be varied depending upon the application required.

The spikes may be located on the mesh at places other than the joints. The mesh may be used in many different situations, for example, as shown in Figures 3 to 5. Referring to Figure 4 the mesh 10 may also be used with conventional fence posts 21. Referring to Figure i the mesh 10 may be laid up to and substantially over a wall 20. This will prevent people approaching and scaling the wall. Referring to Figure 4, mesh 10 may be used to mark a perimeter or boundary of, say, a field 22. Referring to Figure 6, the mesh 10 may be used to mark out: a car park 24.

The mesh may be used to prevent unauthorised access to, for example, railway lines and motorways, without causing obstruction or impairing the view. lt will be appreciated that the uses shown in Figures 3 to 6 are, by way of example only and many other applications (military, security, or otherwise) are possible.

Referring to Figures 7 and 8, the mesh 10 may be stored and subsequently dispensed from a roll 26. The mesh is rolled onto a spindle 28, or drum, with the spikes facing inwards. This ensures that the outward surface of the roll is relatively smooth, and does not present excessive hazard to handlers, for example. In order to dispense the mesh, the spindle 28 of the roll may be mounted between a pair of trunnions 30 which may, for example, be located on the back of a lorry 32. As the lorry moves forward the mesh is laid out on the ground behind the lorry. This method of dispensing the mesh prevents injury to personnel.

It will be appr-eciated that the mesh may be fabricated in other shapes other than those shown. The meshing may have a configuration of diamond shapes, triangles, etc. with spikes at some or all of the joints. The uses illustrated are intended only as examples, as is the method of storing and dispensing the mesh.
